Automakers are offering more fuel-efficient cars than ever

Even with gas prices near their lowest point in more than a decade, Americans are still concerned about the fuel economy of their cars. More than 4 in 5 consumers say gas mileage will be an important consideration the next time they go shopping for a vehicle, according to the results of a new survey conducted by the Consumer Federation of America, which were released Monday. That's no surprise, says Jack Gillis, director of public affairs for the nonprofit organization. "Consumers have had a long history with volatile gas prices," he said. Though motorists have saved approximately $12 billion this year at the pump compared to 2015, according to AAA, car shoppers expect gas prices to rise again in the future. The average respondent to CFA's survey predicted a price of $3.50 per gallon within the next five years, a figure in line with projections made by the US Energy Information Administration. When those consumers visit dealerships, they'll have plenty of options. More models than ever are achieving 30 miles per gallon or more, according to CFA's annual analysis released in conjunction with the survey, and 15 of 16 major car companies improved their fuel efficiency on their 2016 model-year offerings. Only Ford backslid year over year, per the report. Researchers say American consumers are now enjoying the widest range of fuel-efficient options ever offered, in every vehicle class. Of 1,094 models on sale in 2016, 13.4 percent achieved more than 30 MPGs, an improvement from 11.7 percent in 2015. At the same time, the percentage of gas guzzlers offered for sale has declined. The percentage of vehicles on the market that get 16 miles per gallon or less has fallen from 6.1 percent to 4 percent, says CFA. "Even if you're in the market for a large pickup or SUV, you'd have to go out of your way to find a true gas guzzler," Gillis said. ""Consumers have had a long history with volatile gas prices." – Jack Gillis These results, the CFA suggests, indicate federal standards that prod automakers to invest in fuel-efficient technology are having the desired effect. Manufacturers are keeping pace with the requirements of the Corporate Average Fuel Economy standards, which mandate carmakers achieve a standard of 52.5 miles per gallon in testing, equivalent to about 40 miles per gallon in on-road performance, by 2025. CFA's report singled out Mazda as setting an exemplary standard.

Mazda LM55 Vision Gran Turismo reshapes a winning form [w/video]

In the history of endurance racing, there's only ever been one Japanese automaker to win the famous 24 Hours of Le Mans, and as you might have guessed, that was Mazda in 1991 with the 787B – which was, incidentally, the only one ever to win the race under rotary power, or really anything other than a conventional piston engine. That racing success is something Mazda can be proud about, even over two decades later, and it's a badge of honor the automaker is revisiting with the LM55 prototype you see here. Only instead of unleashing it on the Circuit de la Sarthe – or really any actual race track – the Mazda LM55 Vision Gran Turismo is bound only for PlayStation. The latest addition to the Vision Gran Turismo lineup, the LM55 takes inspiration from the aforementioned 787B but gives it a modern KODO design theme. The result is pretty stunning, taking a more radical approach than the Skyactiv Prototype the company is fielding in the United SportsCar Championship or even the dearly departed, head-turning Furai concept. But unlike that diesel prototype and the Wankel-powered 787B, Mazda hasn't specified any kind of novel powertrain for the LM55, fictitious or otherwise - saying only that it has "advanced drive train technology that offers the epitome of power, efficiency and durability and the result is an exceptional power to weight ratio exceeding that of most cars in its class." Just what that class would be we'll likely never find out, but if you don't have a PS3 loaded with GT6 (or, for that matter, even if you do), you can scope out the virtual action in the slideshow above and the rather Christmas-y video below.

Watch what happens inside a rotary engine

Since it looks like Mazda may very well revive the Wankel rotary engine as a range extender for electric cars, there's no better time to become reacquainted with the quirky internal-combustion engine. And there's hardly a better way to become reacquainted than by peering into a running rotary engine, which you can do with the video above. The video comes to us from the YouTube channel Warped Perception. The channel has already shown what happens inside a conventional internal-combustion piston engine by putting a clear cylinder head on top of a flathead engine. This new video shows off the rotary engine by adding a clear side to a tiny model-airplane engine, something that we weren't aware existed and are glad to know about now. Despite the tiny size, the engine is functionally almost exactly like the bigger versions you'll find in Mazdas from about 1967 to 2012. It has intake and exhaust ports on the edges of the rotor housing, and the triangular rotor swings about in a peanut-shaped housing. For maximum effect, jump to right around the 7:40 timestamp. This is the point at which a bit of acetylene is added to the air-fuel mix for a brighter flame. It's at this point that you can really see when the mixture combusts and how the pressure of the flame pushes the rotor to produce rotational motion. Each stage of the video does slow things down to make everything as clear as possible. Even if you already knew how rotary engines worked, it's still fascinating to watch, first because it's something you don't get to see usually, and also because of the engine's elegant simplicity.
